The installation guidance provided here takes into account building the
devices into suitable housing with protection rating IP20 in accordance with
standard EN 60529 or other essential provisions that apply regionally.
• The enclosures must be made of a material with high thermal conduc-
tivity.
• If a control panel with ventilation openings is used, the openings must
be located above and below the variable frequency drive in order to allow
for proper air circulation. Air should be delivered from the bottom and
conveyed outward through the top.
• If the environment outside the control cabinet contains dirt particles
(e.g., dust), a suitable particle filter must be placed on the ventilation
openings and forced ventilation must be used.
The filters must be maintained and cleaned if necessary.
• An appropriate enclosed control panel (without ventilation openings)
must be used in environments containing large percentages or amounts
of humidity, salt, or chemicals.
The DB1 variable frequency drive range can be built in where desired. In
doing so, you must ensure that the cooling system used in the installation
position is capable ofremoving lost heat without this causing the permitted
temperature on the variable frequency drive cooling surface to be exceeded.
